The ways in which a mammal maintains constant conditions inside its body. Maintaining constant internal conditions is vital to the survival of a mammal. Cells in any living mammal will only function properly in the correct conditions. The environment of a mammal is variable and this variation could be a key problem if cells were susceptible to the changes in the external environment. An approximately constant cellular environment must be maintained for efficient functions of cells and to give independence from the environment; homeostasis allows this to be achieved. Homeostatic mechanisms use negative feedback to maintain the constant levels within the mammal. Changes in the internal environment trigger a response, which a receptor detects, that counteracts the change, by use of effectors; the corrective mechanism is triggered by the very substance that is being regulated. Having separate mechanisms for the regulation of certain conditions allow for a greater degree of control....
